Событие directionError не запускается в картах Bing

Я использую карту Bing, чтобы рисовать маршруты грузовиков. Но directionError никогда не срабатывает, даже если маршрута для двух местоположений не существует.

 Microsoft.Maps.loadModule('Microsoft.Maps.Directions', function () {
            directionsManager = new Microsoft.Maps.Directions.DirectionsManager(map);
            directionsManager.setRequestOptions({
                routeMode: Microsoft.Maps.Directions.RouteMode.truck
            });
            //Create waypoints to route between.
            var waypointA = new Microsoft.Maps.Directions.Waypoint({ address: pickup_address });
            directionsManager.addWaypoint(waypointA);
            var waypointB = new Microsoft.Maps.Directions.Waypoint({ address: destination_address });
            directionsManager.addWaypoint(waypointB);
            //Add event handlers to directions manager.
            Microsoft.Maps.Events.addHandler(directionsManager, 'directionsError', directionsError);
            Microsoft.Maps.Events.addHandler(directionsManager, 'directionsUpdated', directionsUpdated);
            //Calculate directions.
            directionsManager.calculateDirections();
  });

function directionsUpdated(e) {
        console.info(e);
}
    //---------------- Direction Error --------------//
function directionsError(e) {
        alert('Error: ' + e.message + '\r\nResponse Code: ' + e.responseCode)
 }
